Ok, FWIW - yes this was a serious situation, but Chilpo is not exactly a tourist spot. You do have to travel through the city going from MEX to Acapulco. Protests are not uncommon, but they are usually nothing like this. As an aside, the police were rescued, schools reopened and government forces are providing security to the city.

As for the DNT advisory from State. IMO outdated and needs to be revised. 5 years ago I would have cautioned people from travelling to Acapulco. The situation has gotten better to the point there are less homicides in Acapulco per capita in the last 12 months than in Cancun, which has not restriction besides "be careful at night". Same thing with Ixtapa/Zihuatenejo and Tulum. Objectively safer vs Tulum over the past 12 months, but same mismatch of restrictions.

The larger area of Guerrero (minus Taxco) has never been a tourist destination, and having a DNT make little difference (although the state is trying to open up tourism on the costa chica beaches between Acapulco and Oaxaca). But the advisories on the tourist cities are taking their toll.
